OK, let me make sure I understand. Say I'm meeting a good friend for a meal-I'm on the dining plan, but she isn't. I told her I'd "pick up the check", treat her to the meal. There's no way to do that at a TS restaurant? Could I do that a QS? If I'm buying for my family, and send them to find a table, while I get the meal, do I have to bring all their MBs, or can I put everything on my MB?
